Answers:A) The graph of the function is increasing over the interval 0 < t < 3B) The graph of the function is increasing over the interval 14 < t < 18C) The graph of the function is decreasing over the interval 3 < t < 14D) The graph has a max value of V = 7 at t = 3E) The local min (V = 1) occurs when t = 14F) I'm not sure what your teacher is trying to say here. There isn't a local max or local min when t = 18. Seems like a typo. If you ignore the "local max" part and you're only wanting the value of V, then V = 4 here.

Explanation:

The graph goes uphill as you read from left to right over the interval 0 < t < 3. This means t is between 0 and 3. So the graph is increasing over this interval. The same applies for the interval 14 < t < 18 as well.

The graph goes downhill we we are between t = 3 and t = 14, so that's why the graph is decreasing on the interval 3 < t < 14.

The local min is the lowest point of the graph. For sine functions like this, they occur infinitely many often. But we're restricting to just one cycle (so to speak) and we only have one local min at (t, V) = (14, 1). So that explains the answer to part E. The answer to part D is similar but we're looking at the highest point this time at (3,7)

As for part F, it seems like your teacher made a typo because the graph is neither at the highest nor the lowest point when t = 18. The graph is right in the middle instead.

Answer from: Quest

step-by-step explanation:

by observation, we can see that the the graph is simply the graph of y = |x| that has been shifted 4 units downwards and 3 units to the left.

we can recognize in choice d :

y = | x + 3 | - 4 (rewriting in general form)

y = | x - (- 3) | - 4

the "-4 " term means that the graph has been shifted by 4 units in the negative y direction

the "-3 " term means that the graph has been shifted by 3 units in the negative x direction

this matches our observation of the graph described above.

If its non of them tell me..valerie took a day-trip. she drove from her house for a while and took a coffee break. after her coffee break, she continued driving. after 2 hours of driving after her coffee break, her distance from her house was 210 miles. her average speed during the whole trip was 60 miles per hour. valerie created the equation y−210=60(x−2) to represent this situation, where xx represents the time in hours from her coffee break and yy represents the distance in miles from her house. which graph correctly represents valerie's distance from her house after her coffee break?
